• Etape 1: vérifier l’état des TBS et rechercher le nom du fichier à modifier.

Exemple de requete generique reutilisable:

select a.tablespace_name                                           			        Tablespace,
	   b.tablespace_name                                              				"Nom TBS",
     ddf.file_name                                                          "Nom Fichier",
     ddf.autoextensible                                                       "Auto extend",
	   sum(b.bytes)/1024/1024/count( distinct a.file_id||'.'||a.block_id )      	Total,
	   round(sum(b.bytes)/1024/1024/count( distinct a.file_id||'.'||a.block_id ) -
	   sum(a.bytes)/1024/1024/count( distinct b.file_id ),2)			  used,
	   round(sum(a.bytes)/1024/1024/count( distinct b.file_id ),2)                   Libre,
	   round(100 * ( (sum(b.bytes)/count( distinct a.file_id||'.'||a.block_id )) -
			   (sum(a.bytes)/count( distinct b.file_id ) )) /
	   (sum(b.bytes)/count( distinct a.file_id||'.'||a.block_id )),2) 				Pourcentage 
from sys.dba_free_space a, 
sys.dba_data_files b, 
dba_data_files ddf 
where a.tablespace_name = b.tablespace_name
and   b.tablespace_name=ddf.tablespace_name
group by  a.tablespace_name, 
          b.tablespace_name,
          ddf.file_name,
          ddf.autoextensible
order by Pourcentage desc;
